The embodiment of the invention relates to an anti-creeping energy absorption device for a train. The anti-creeping energy absorption device comprises a mounting base, an energy absorption element andanti-creeping teeth; the energy absorption element comprises an expansion pipe, a pressurizing pipe, a hydraulic triggering device and a hydraulic device; the bottom end of the expansion pipe is sleeved on the mounting base; the tail part of the pressurizing pipe is arranged in the expansion pipe; the anti-creeping teeth are mounted at the top of the pressurizing pipe; the hydraulic triggering device is arranged at the bottom of the pressurizing pipe; the hydraulic device comprises a cylinder barrel and a hydraulic ejector rod; after a train is collided, the anti-creeping teeth are meshed with the anti-creeping teeth of a collision train, the anti-creeping teeth and the pressurizing pipe move towards the expansion pipe under the action of impact force, and gas is extruded to generate first reverse acting force; the hydraulic triggering device is connected with the hydraulic ejector rod, and a fluid medium is compressed to generate second reverse acting force; the bottoms of the anti-creeping teeth are connected with the top of the expansion pipe, and the expansion pipe expands and tears, and curls along the mounting base to generate third reverse acting force; and the directions of the first reverse acting force, the second reverse acting force and the third reverse acting force are opposite to the direction of the impact force.

    本发明实施例涉及一种列车防爬吸能装置包括:安装座、吸能元件和防爬齿;吸能元件包括膨胀管、加压管、液压触发装置和液压装置;膨胀管的底端套接在安装座上;加压管的尾部设置在膨胀管内;防爬齿安装在加压管的顶部;液压触发装置设置在加压管的底部;液压装置包括缸筒和液压顶杆;列车碰撞后,防爬齿与撞击车的防爬齿啮合,冲击力使其连同加压管向膨胀管运动,气体被挤压,产生第一反向作用力;液压触发装置与液压顶杆相接,流体介质被压缩,产生第二反向作用力;防爬齿的底部与膨胀管的顶部相接,膨胀管产生膨胀、撕裂,并沿安装座发生卷曲,产生第三反向作用力;第一反向作用力、第二反向作用力和第三反向作用力的方向与冲击力的方向相反。
